# --description--

To populate the forum leaderboard with data, you will need to request the data from an API. This is known as an <dfn>asynchronous</dfn> operation, which means that tasks execute independently of the main program flow.

You can use the `async` keyword to create an asynchronous function, which returns a promise.

```js
const example = async () => {
  console.log("this is an example");
};
```

Use the `async` keyword to create an asynchronous arrow function called `fetchData`.

# --hints--

You should use the `async` keyword to create an asynchronous arrow function called `fetchData`.

```js
assert.match(code, /const\s+fetchData\s*=\s*async\s*\(\s*\)\s*=>\s*{\s*[^}]*\s*}/);
```

`fetchData` should be defined.

```js
assert.isDefined(fetchData);
```

`fetchData` should be a function.

```js
assert.isFunction(fetchData);
```
